Hi Yves,

I'm quite new to this PHP, XML sutff. Therefore I'll will need a more 
detailed information what you mean (actually I don't get the idea).

Greetings,

Stefan.

BTW, about the wiki I still have no idea how to contribute. In my 
opinion is the wiki something that is no so important. A help (which 
could be later on adopted in the wiki) seems to me more important. 
However, right now I think it's better to make RKWard more popular and 
to extend the functionality by plug-ins. Making it more usable makes it 
more attractive to people with less interest in the technical part. But 
these might be more interested in writing stuff for the wiki. What do 
you think?
